Selecting a Device
When the Tracer application starts, it attempts to open all attached readers. Each attached
reader is listed separately in the Device menu. If no readers are found, the application displays
a warning and the Device menu is empty.
The reader that is found first is automatically selected as the active device. The name of the
active reader device is always displayed on the window caption. To change the active reader,
make a selection from the Device menu as shown in the figure below.
Controlling a Device
The Device Menu
After making a selection from the Device menu, you can control the active reader from the
Reader Control menu or from the floating Control Panel. The figure below shows the Control
Panel buttons and describes the actions they perform.
